This invention appertains broadlyto new anduseful improvements in nternal combustion engines and has more specific reference to a novel and Simplified rotary valve forfusein connection therewith.

' The primaryobject of the present inven-i tion is to improve generally'the construc- I tion of valves of the character stated whereby to provide a valve' structureolf increased etliciency and durability, one which is' extremely simple in its constructionand which can be manufactured at a small cost and one which can be incorporated with internal combusion engines of one or a plurality of cylinders.

Another object of the present invention is to provide such a rotary valve which constitutes both an intake and an exhaust manifold and further to provide a novel parti- 2 tion wall for separating the intake and exhaust manifolds. v a

Another object of the present invention is to provide such a valve which may'have associated therewith blower fans disposed in the intake and exhaust manifolds,

In this form of. theinvention, the letter G generally indicates the cylinder head andH the improved valve associated therewitln The cylinder head, is, of course,

The Spiral formation of pa titionwaH :54 is'aiiessentialfeaturefof the present in sa si de valve mountedon the side vention because it not only serves to bring the intake and exhaust manifolds over the engine ports at the proper time but also tends to draw in the fresh charge of fuel and expel the used charge.

With particular reference to Figures 9 to 15, wherein is illustratedanother modified form of the invention, the letter vgenerally designates an engine cylinder 'head having a substantially cylindrical valve casing 59 formed thereon. AIPOItYGOLlS formed in the cylinder head for the passage of combustible gases therethrough. This form of the invention embodies a main sleeve valve (S1 of cylindrical form provided with 'a central partition 62. This main sleeve valve or rotor 61 isformed with a air of spiral ports, comprising an intake port 63 and an exhaust port 64, terminating adjacent the rear end of the rotor, V

Disposed between the rotor 61 and the casing 59'is a'cylindrical auxiliaryvalve sleeve 65 formed with apluralityof staggered or alternately arranged ports 66 of rectangular formation the -sleeve being adapted to be rotated in reverse movement to the rotation of the rotor. V

This valve structure is operated bymeans of beveled-gears '67 and. 681mounted on the forwardends of the rotor and auxiliary sleeve respectively. When the rotor and sleeve .68 are in assembledposition as shown partition formed in the valve body providing intake and exhaust manifolds, a sleeve rotatably positioned about the valve body and formed with a plurality of ports adapted for selective registration with the main valve ports, beveled gears fixed on the forward ends of the valvebody and sleeve, and a .drive pinion in mesh with i the said beveled gears to rotatably operate the valve "body and sleeve in reverse rotary movement.

in Figurefl5, the forward end of the rotor p 7 projects substantially forward of the .auxiliaryv sleeve so that the beveled gears 67 and 68 are disposed inparallelspaced;posi tions. Thesegears are designed-to mesh with a beveled pinion 69, fixed upon the upper end of -a;pinion shaft :70 which is suitably connected with the crankshaft of the motor. V I v In operation, if'the rotor is arrange'd'to rotate in an anti-clockwise direction, the auxiliary ;outersleeve' 68 rotates in a clockwisef direction. 'Thespiral ports-63 and'64 .and tlie rectangular ports 66 are formed so as to selectively register in cooperation with the timing system to admit acombustible' charge into the'icylindersor permit escape of the exhaust. It. will'thus be noted that the partition 62 divides the main sleeve valve or rotor to form-intake and exhaust manifolds, whereby the intake charge 1s conducted through the intake manifold into the cylinders and the exhau'st carried through the exhaust manifold to. the. muflier.
